Researchers from the Harte Research Institute for Gulf of Mexico Studies (Texas A&M University-Corpus Christi) and TAMU’s Geochemical and Environmental Research Group recently completed two research cruises (Oct. 25-28; Dec. 2-4, 2022) in the northwestern Gulf of Mexico to examine ocean acidification (OA) conditions. Scientists led by GCAN Steering Committee Co-Chair Dr. Xinping Hu of TAMU-Corpus Christi took physical and chemical measurements in waters from the nearshore to about 1000 m depth. They also brought samples back to the lab for later analysis. During the December cruise, they also deployed a wave glider to monitor the Flower Garden Banks area and survey surface waters for pH and carbon dioxide levels.
